The aim of this action research project was to improve student learning by encouraging more "time on task" and to improve self-assessment and feedback through the introduction of weekly online tests in a Year 2 lecture module in biological sciences. Initially voluntary online tests were offered to students and those who participated…

Purpose: The purpose of this study was to describe the current school computer access rates of elementary school students and to determine the extent to which school computer access relates to academic achievement among Grade 5 students in the state of Texas. Specifically, the relationship of school computer access to student passing rates on the…

This mixed-methods study was designed to compare the achievement in mathematics and reading to that in science since the enactment of No Child Left Behind (NCLB) in 2002. The literature discussed that due to the increased emphasis in mathematics and reading due to NCLB, science education was impacted. Science instruction has endured reduced…

Many college students struggle with first-semester general chemistry. Prior studies have shown that a student's prior knowledge of chemistry, a cognitive factor, does not account for the total variance when measured by examination scores. This study explored the role of self-regulated learning (SRL) to identify the degree of success or failure of…

The ability to solve problems in a variety of contexts is becoming increasingly important in our rapidly changing technological society. Problem-solving is a complex process that is important for everyday life and crucial for learning physics. Although there is a great deal of effort to improve student problem solving skills throughout the…

Terms to be familiar with before you start to solve the test: polymerase chain reaction, DNA amplification, electrophoresis, breast cancer, "HER2" gene, genomic DNA, "in vitro" DNA synthesis, template, primer, Taq polymerase, 5[prime][right arrow]3[prime] elongation activity, 5[prime][right arrow]3[prime] exonuclease activity, deoxyribonucleoside…

Terms to be familiar with before you start to solve the test: human papilloma virus; cervical cancer; oncoproteins; malignant transformation; retinoblastoma protein; cell cycle; quiescent and cycling cells; cyclin/cyclin-dependent kinase (Cdk) complexes; E2F; S-phase genes; enhancer element; proto-oncogenes; tumor suppressor genes; radioactive…

The purpose of this study is to investigate the effects of a ubiquitous problem-based learning system (UPBLS) on students' question-raising performance in field inquiry activities. An experiment was conducted on an elementary school natural science course. A total of 43 sixth and fifth grade elementary students divided into experienced and…

Given the increasing costs associated with commercial textbooks and decreasing financial support of public schools, it is important to better understand the impacts of open educational resources on student outcomes. The purpose of this quantitative study is to analyze whether the adoption of open science textbooks significantly affects science…

Assessments of U.S. students typically reveal stronger performance in science than mathematics yet their science performance remains uninspiring at best. Whether the metric considered is an international benchmark from TIMSS or PISA or the nation's NAEP report card, the mediocre portrait of U.S. science achievement has remained virtually unchanged…

This report explains that The Elementary and Secondary Education Act (ESEA)--known since 2001 as No Child Left Behind (NCLB)--requires states to set annual objectives for increasing student achievement in reading and mathematics and closing achievement gaps among student subgroups. Under the flexibility waiver granted by the US Department of…

This webinar explored how the Next Generation Science Standards (NGSS) provide an instructional framework to support professional growth and inform teacher evaluation systems for science instruction. This Q&A addressed the questions participants had for Dr. Wilson and Jody Bintz following the webinar. The webinar recording and PowerPoint…

A report providing an update on the state of the research on testing accommodations as well as to identify promising future areas of research. Previous reports by NCEO have covered research published since 1999. NCEO summarizes the research to review current research trends and enhance understanding of the implications of accommodations use in the…

There is much debate over the impact of high stakes testing as well as a growing body of research focused on both the intended and unintended consequences of these tests. One claim of both the popular media and education researchers is that high stakes tests have led to curricular narrowing--the idea that school time is increasingly allocated to…

The question of whether marking speed is related to marking accuracy is important for training examiners and planning realistic marking schedules. We explored marking speed in the context of a past examination for an international biology qualification for 14- to 16-year-olds. Forty-two markers with differing backgrounds experimentally marked 23…
